GENERAL DESCRIPTION

The NJU3719A is a 24-bit serial to parallel converter

especially applying to MPU outport expander. It can

operate from 2.4V to 5.5V.

The effective outport assignment of MPU is available

as the connection between NJU3719A and MPU using

only 4 lines.

The serial data synchronizing with 5MHz or more

clock can be input to the serial data input terminal and

the data are output from parallel output buffer through

serial in parallel out shift register and parallel data

latches.

The hysteresis input circuit realizes wide noise

margin and the high drive-ability output buffer (25mA)

can drive LED directly.
